Significant Non-Barrier Culverts
High Priority
Site 7 is located on a unnamed stream in the Boss sub-basin near the confluence of Ryan Creek. This site was selected because an improper placement of a culvert has caused the creek to run alongside the road for over 20 m. This site introduces a significant amount of sediment into Boss Creek. Rainbow trout have been sampled upstream which indicates that the culvert is only a partial barrier. The diverted channel appeared to be greater in width than the old dry channel. This may be attributed to the addition of runoff collected alongside the 620 road which was directed towards the new channel.
Site 9 is located on Hendrix Main near the confluence of Deitrich Creek. Beaver activity blocked the culvert intake in the spring of 1997. The water levels backed up by the blockage had risen to a height which threatened the road. Weldwood removed the blockage and the water levels dropped. Removal of the blockage resulted in the exposure of large amounts of sediment which may impact on the high value rearing habitat at this site. An opportunity for the enhancement of rearing habitat for juvenile rainbow trout exists. The good access would facilitate the addition of anchored LWD placements, a beaver control structure and grass seeding.
Moderate Priority
Site 17 is located on the 720 Rd on an unnamed stream which drains into No Name Lake.
The culvert is not a barrier at present but the continued accumulation of debris and sediment at the intake may eventually block the culvert. A small section of spawning habitat exists upstream of the culvert. Although the area of the spawning habitat is limited, it may be important habitat for residents of No Name Lake because other spawning opportunities in the vicinity appear to be limited.
